Filed Dec. 21; 1940 INVENTOR: 4 HERMA BY KML mWw Patented July 28, 1942INFUSION CONTAINER Hermann Schiess, Basel, Switzerland ApplicationDecember 21, 1940, Serial No. 371,090 In Switzerland January 27, 1940 8Claims.

The article, object of the present invention, is an infusion containerfor tea and other beverages, particularly suitable for the cateringtrade, with a lid and a container shaped in low cylindrical form whichare put together on one side, and on the other side have a bottom, eachof these bottoms protruding inwards and forming a collar destined forthe reception of the holder, whereby both parts, i. e. the lid and thecontainer, are held together in this collar by means of a rivet.

With an infusion container constructed as set forth above, the fasteningpoint of the lid and the container is thus hidden and is inaccessible sothat the rivet forming the connection between these parts cannot bebroken, not even with a special tool, without, at the same time,breaking the other parts surrounding the collar. Moreover, the specialform of the container ofiers the great advantage that one and the samestamping tool with the corresponding die, suffices for the manufactureof both the lid and the container.

An example of an execution of the article according to the invention isillustrated in the drawing in which:

Fig. l is a cross sectional view of the container according to theinvention and shows a part of the holder in a position ready forinsertion into the container,

Fig. 2 is an illustration of the container viewed from above in thedirection of arrow II in Fig. 1,

Fig. 3 is a side-view of the container with a holder inserted therein,and

Fig. 4 illustrates the container with a flexible holder.

Like parts are designated by like numerals in all figures.

Figs. 1-3 illustrate the container I having perforations 2 in the formof radially-placed narrow slits and permitting access of water to theinfusion matter and the lid 4. Part I and part 4 is each provided with ahollow stem or collar portion 5, each of said portions having a slightlyconical bore into which a solid holder in the form of a handle with apiston-shaped cylindrical end may be inserted temporarily. The containerl and the lid 4 may be made of light metal or a Bakelite material which,even when subjected to certain changes of temperature as, for instance,when dipped into hot water, remain completely odorless andtasteless. Thelid 4 and the container l are of exactly the same shape and appear aslow cylinders 4a which, on one side only have a bottom la in the form ofa flat cone. The outer rims l6 and 4b of parts I and 4 are of increasedthickness and abut one another and form a circular-shaped joint l5. Theends of the inwardly projecting collar or hollow stem parts 5 are eachprovided with an inwardly projecting collar I0 and 40 respectivelyseparating the inner part of the container and do not reach quite as farinward as the joint l5, so that a small space remains between the twocollars I0 and 40, as can be seen in Fig. 1. This is intended to preventany cracking of the container when riveting the lid and containertogether. A rivet I6 is inserted in the small opening of collars lo and40 which rivet holds the two parts I and 4 firmly together so that theycannot be separated one from the other, without breaking the rivet andsurrounding parts.

This rivet I6 is hollow and its outside diameter is somewhat smaller.than the diameter of the bore in the collars lo and 4c. The ends of thehollow rivet are bent outwards at about as illustrated in Fig. 1. Theoutside diameter so applied to these bends touches the inner surface ofthe hollow portions 5, thereby centering both the container l and thelid 4. The rims lb, 41) of the container I, as well as of the lid havean outwardly protruding reinforced edge where the rims meet, whichprevents any jamming of the containers if these are, as intended, packedone on top of the other in tubular storing containers.

The construction of the container in the manner described offers the twofollowing advantages: (a) that for the manufacture of the two parts Iand 4 only one stamping tool or casting mould is required according tothe process used, and (b) that the holder can be fastened either in thelid or in the container.

The infusion container as per Fig. 4 is substantially the same as thatshown in Figs. 1-3, the only difference being another kind of holder,such holder consisting of a flexible material as, for instance, cottonthread, wire, a small chain or a similar article, which is fastened to aremovable stopper IB inserted in the hollow stem portion of the lid 4.

The size of the containers is ample to allow the infusion material ormatter contained therein to expand. The long, narrow slits ofier theadvantage of properly withholding the infusion matter in spite of theample section for the water circulation, which is not the case with theusual system of small round perforations.

Having now particularly described and ascertained the nature of myinvention, and in what manner the same is to be performed, I declarethat what I claim is:
